wiring diagram question for 1964 K20

[82sdale]

does anyone know the the difference between wiring diagrams numbered MD-94010 and MD-94124? These wiring diagrams come from a service manual for a 305 6 cylinder GMC. Which models, specific accessories etc would apply to which diagram or any other specific information as to the differences would be appreciated...thx...tim

What shop manual did it come from? what year and truck are you looking for? what specific wirirng are you looking for? I will look in mine it is the gmc factory manual, with the supplement for later years and see if I can help, the gmc vs chevy are a little different. If I remember the gmc one I have has the model in the description of the wiring schematic. I will try to look at it later tonight.
